- One reason time seems to go faster when you are older. “Has it already been a year?” You have so many more things going on and only a few of them can reside in working memory. When some milestone brings a buried one back to the surface it feels like time has passed more quickly than if it were on your mind the whole time.
- A 50 meter tall swimmer would win every race. Generally taller swimmers have less ground to cover and so the distance is shorter for them. Is there any kind of race other than swimming like that?
- If you have your brain cut into two parts so that one side is unaware of what the other is doing can you tickle yourself?

In powerlifting, shorter lifters have to lift the weights less distance (and the weight is also easier to lift because of shorter lever arms)

Imagine an 800m running race on an oval track. How would a sufficiently tall person (with a stride long enough to carry him/her from any point on the track to any other point on the track) register the fact that he has run a lap? In other words, what is the minimal number of points on the track at which s/he is required to stand to register a valid lap? The answer can’t be 1 because a normal human can already achieve this by crossing the finish line backward and then forward.

2. As people get bigger, the squared/cubed problem becomes bigger and their bodies become harder to cool (less surface area/mass ratio). In long distance running cooling your body fast enough to avoid fatigue is a major problem, so somewhat tall, but very thin runners tend to win. In shorter distances, more stocky runners win.
3. Yes. You can do this by cutting off blood supply to an arm so it goes numb. No brain surgery required.
